读取由Start-Process创建的stdout/stderr文件内容 不使用 Start-Process 并使用the call operator,& 不使用 Start-Process 并使用 .NET 对象启动进程 第一种方式如下所示: $myLog = "C:\File.log" $stdErrLog = "C:\stderr.log" $stdOutLog = "C:\stdout.log" Start-Process -File myjob.bat -Redire...
/do/error 2>/tmp/err.msg 使用 Write-Error 写入stderr。要将stderr重定向到文件使用: Write-Error "oops" 2> /temp/err.msg 要么 exe_that_writes_to_stderr.exe bogus_arg 2> /temp/err.msg 请注意,PowerShell将错误写为错误记录。如果您想避免错误记录的详细输出,您可以自己写出错误信息,如下所示:...

The Success and Error streams are similar to the stdout and stderr streams of other shells. However, stdin is not connected to the PowerShell pipeline for input.PowerShell redirection operatorsThe PowerShell redirection operators are as follows, where n represents the stream number. The Success st...
PowerShell 7.4 changed the behavior of the redirection operator when used to redirect the stdout stream of a native command. For more information about redirection, see about_Redirection.ExamplesExample 1: Send output and create a fileThis example shows how to send a list of the local computer'...
itself. Native commands (meaning executables you run directly) will write output to STDERR or STDOUT pipes. However, if the output is not redirected, PowerShell will simply have the native command write directly to the console. PowerShell can’t just always redirect the output to capture it ...
在类Unix的平台上，使用外部程序输出，js2010's eleganttee /dev/ttysolution是最简单的。
# Includes a redirect of STDERR to STDOUT so we can capture it as well. $output = cmd /c mklink $mkLinkArg `"$Link`" `"$Target`" 2>&1 if ($lastExitCode -ne 0) { throw "MKLINK failed. Exit code: $lastExitCode`n$output" ...
Start-Process .\x64\Debug\CountBytes.exe -RedirectStandardInput .\generate_hprof\heap.dump.hprof Windows - Output shows up in console, but disappears, It turns out the program in question wasn't flushing stdout after doing a printf to it. Apparently, cmd is willing to flush that buffer whe...
Instead, this example uses System.Diagnostics.Process to start powershell.exe as a process, and redirect stdin, stdout, and stderr. The result of those things is displayed in a WPF TextBlock.The key bit is the Shell class, which I show here. It includes async i/o for the output...
